SPECIFICATION forming part of Letters Patent No. 663,545, dated December 1 1, 1900.

Application filed June 22, 1900.

Z all whom it may concern:

Be it known that I, FRANZ E. JAEGER, a subject of the Emperor of Germany,'residing in the city, county, and State of New York,

have invented certain new and useful Improvements in Looks for Multibarrel- Firearms, of which the following is aspeeificat-ion.

1 My invention has relation to a lock or ham- I0 mer mechanism for firearms having a plurality of barrels; and the object of myinventio'n is to provide a mechanism whereby an ondinary multibarreled gun can be fired in the usual manner-viz, by pressing the front or right trigger the right barrel is discharged or by pressing the left trigger the left barrel is discharged, or it is adapted to fire the right and left barrel by pressing the front trigger twice, once for each barrel, orthe reverse order for left and right barrel may be used by pressing the rear trigger twice, once for each barrel.

My invention therefore consists in the construction and novel combination of parts whereby the foregoing results can be accomplished.

In the drawings forming part of this specification, Figure l is a side elevation of the frame of the gun, with the part of the barrel connected tlerewith, partly in section. Fig. 2 is an inverted plan View of" the frame and upper tang with the trigger plate removed,

looking in the direction of the arrow a, Fig. i

1. Fig. 3 is a longitudinal sectional view taken approximately on the line 3 3, Figs. 1 and a. Fig. 4 is a perspective view of the frame, showing the triggermechanism. Fig. 5 is a plan View of the frame with the upper tang removed, showing the sears in the position which they will occupy when the right sear has been fired and the tripper-block dropped and engaging the left sear preparatory to firing the left barrel by'the right trigger. Fig. 6 is an enlarged perspective view of the triggers and their method of support. Fig. 71's an end view of a portion of the frame, showing the two sears, the bridge-bolt, and the tripping extension therefrom. Fig. 8 is an enlarged perspective view illustrating the connection of the tripper-block and spring, the position of the sears indicating the left Serial No. 21,193. (No model.)

dicating thereverse of the operation illustrated in Fig. 8 and wherein the right barrel has been fired bythe right-hand trigger, the

sear for the'left trigger being in a position for firing the left barrel by the movement of the right or front trigger. Fig. 10 is a perspective view illustrating the connection of the right sear -with the tripper-block and spring, the left barrel having been fired by the left trigger, the right ready through the lef trigger; Fig. l1 is an inverted longitudinal sectional view of the upper portionof the frame approximately on the line at t Fig. 12; and Fig. 12 is a transverse sectional elevation on the line-5 5, Fig. 1l. Fig. 13 is a section andplan of the rear end of the frame.

Fig. '14: is a perspective view of the bridgebolt-opcrating means. Fig. 15 is a like view of the bridge-bolt'and its operating means combined, and Fig. 16 is a like view of the bridge-bolt detached.

Similar numerals of reference indicate corresponding parts throughout the several views.

The improvements herein recited embrace two or more sears, with means for cooking the hammers, simultaneously raising the rear or operative ends of'the scars, and further means (specifically a retractile tripper-block) for automatically connecting the rear ends of the sears, whereby either trigger will initially vibrate the sear-say the right-With which it first comes in contact and then on a repetition of the vibration operate the left sear.

The improvements also embody means which in the present instance is utilized from a part of the gun ordinarily employed for the purpose of locking the barrels to the stock and unlocking them, whereby after .the discharge'of either or both of the barrels, which involves the vibration of eitheror both of the sears, the tripper-block willbe moved outwardly, so as to allow the tripperblock to assume what I shall call its intermediate or normal position.

From the foregoing and as hereinafter pointed out it will be apparent that my specific improvements embody means for automatically connecting and disconnecting the tion, f.-

ends ofthe hsnal sears and adding to the looking or bridge bolt or equivalent mechanism an extension for operating this connecting means.

5 I have illustrated, therefore, the parts of a gun of usual construction and which are adapted to cooperate with my improvements; but it will be clear thatuny improvements may be embodied in guns of-ot-her construc- In the drawings forming part. of this specification, 1 is the trigger-plate, provided with a lurality of triggers 2 3, there being two in this special instance, 2 being the' right or forward and 3 the left or rear trigger, the forward portions or noses 5 6 of'the trigger-' shanks 7 8 being pivoted tothe pin 9 in the block 10, the trigger oil-the right-hand side having its finger-hold 11 more forwardly pre- .20 sented than the one on the left-hand side,

whose finger-hold 12 is at the rear, whereby they are termed forward and rearward triggers, both trigger-shanks passing through slots13 14 in tlie'irigger-plate. A retainingspring 15, Figs. 3, 4, and 6, secured to'the "trigger-plate 16 and having its free ends secured to the trigger, is also present. This holds the triggers in their proper places and ,prevents them'from dropping. The rear or 0 left trigger 3 is'p'rovided with a projection 0 through the se'pturns'23 24, their forward ends being adapted to engage when the hammers are cooked, as shown in Fig. 1', a nipple or lug 25 extending from the hammers 26 near their pivoting-pins 27, all in the usual way.

5 The usual mainspring 26, with its tooth 26" engaging the hammer in'the usual way, is also present. The hammers forward of the lug 25 are recessed or notched, as at 28, to provide means for allowing the forward ends 18 19 of the sears a further orsupplemental downward movement after discharge.

At 29 is the cocking-lever, pivoted on the pin 50 and of the usual construction, its nose 25) being adapted to engage an aperture 30 inthe muzzle-butt 31 ofthe gun, the rear extension 32 of which engages the forward projection 33 of the hammer in the usual way. A 34 'is the bridge-bolt usually employed for the purpose of lockingthe barrels to the frame. "This bolt is adapted to be reciprocated forwardly anjd 'rcarwardly and guided in the usual manner by'the upright rod 35, the bolt resting on the rocker-arm 36 and is held in place by pin ecoentrically engagingthe bolt, the reciprocation being caused by the eccentric movement of the pin 37, the upper end of the rod being secured to the Theright sear is not.

I lever 38, having a hub 39, provided with a shoulder-recess 40, engaging the free end of a spring 41, fastened in the frame, all operating in the usual way. I

The rear end of the bridge-bolt 34-is provided with an extension or arm 42, acting as a retractor for the tripper-block, to be described, and which is normally in line with gage with an upwardly-extending lug '44, formed on a fiatspring, the inner end 46 of which is secured by a screw 47 to the righthand sear 18, and at the end of the spring formed the Tripper-block, having shoulders 49 50 formed on'the upper and lower surface jection 51, forming an intermediate recess'52, into which the rear end 53 of the right-hand sear '18 rests, so as to form a support for the end of the tripper during" the latters movement transversely relatively to the ends of the sears, while the rear end of the left sear 'point 54.

.The spring 45 and trippenbl'ock 48 may be sion 42 from the bridge-bolt. The operation is as follows: The lever 88 being vibrated, moving the bridge-bolt against the stress of the spring 41, so as to break the gun-joint, and sim ultaneously moving the pro-- by a like change in the location of the exten- 44 on thespring, thereby forcing it to spring sidewise or laterally against its tension, and thus moving. the tripper-block 48 away from its engagement with the point 54 of the lefthand sear 19, the block being moved upon the end of. the right-hand sear 18 as a guide, and whenever the lever 38 is released and the bridge-bolt retracted the spring will force the intermediatenose or projection 51 of the tripper-block against the point 54 of the left-hand sear, thereby holding the tripper-block in its intermediate or normal position. The discharge of either'or botli barrels leaves either the'left-hand-searpoint on top of the nose of the tripper-block or, reversely', the nose of the tripper-block on top of the left-hand-sear point, and the rearward movement. of the bridge-bolt and its extension throws out the tripper-blockto free the nose from the searpoint, allowing the searspring to vibrate the rear end of the sear downwardly to bring it in line with the projection of the tripperblock,or, reversely, should the discharge have left the (ripper-block on top of the left-hand sear the rearward movemeptof the projection 42 will free the tripper-o ock from the leftdown and bring the noserof the tripper-block into contact with the left-hand-sear point, so that simultaneously with the operation of breaking the gun the tripper-block is inoved out of engagement-with the left-hand sear, or

- vice versa, allowing the rear end of either of (which I shall call the tripper-spring) is thereof, connected by a vertical walLor pro- Y 19 is provided with an inwardly-projecting secured toeither sea'r,if desired, accompanied hand sear, allowing the right sear to dropand adapted to have its cam-like end 43-en-.

jection 42 rearwardly causes it to strike thelug the sea rs to vibrate downwardly, bringing the tripper into its normal or intermediate position, the gun being broken at the joint, and, further, upon breaking or opening piiotal movement ofthe parts cocks the hammers and elevates the rear ends of the scars. The gun parts are then in posit-ionto permit either trigger to be vibrated, say, to discharge the right and left barrel by the right trigger or left and right barrel by the left trigger, or both barrels from both triggers, as righttrigger for the right .barrel and left trigger for the left barrel. When the sears are ready for distact with the lower side of the tripper-block,"

(which, being deeper than the sear-plate 19, does not require the lug 1 7, which is formed n pen the trigger-shank 8,) elevating the rear end of the sear 18 through its connection with the recess 52 of the tripper-block, depressing the forward end 18 of the sear 18 from the dog 25 against the stress of the sear-spring 19 on the hammer, allowing the mainspring 26 to vibrate the lower end of the-hammer, forwardly moving the upper end of the hammer for discharge, so as to bring the recess or notch 28 in the hammer in line with the forward end 19 of the sear, the sear-spring 19 then forcing the forward end sear into the notch,

thus providing for it an excess of vibrationover the discharging impulse, moving down-.

wardly the rear end of the sear until the upper shoulder 49 of the tripper-block lies below the plane of the left-hand sear-point 54.. The tripper-spring, which has been distended, as

previously described, forces the tripper-bl'ock underneath the left-hand sear-point, which bridges or connects the ends of the scars, so that another complete vibration of the right or forward sear brings the trigger-shank against the tripper-block, vibrates the rear of the left-hand sear, freeing the hammer and discharging the barrel, as previously described. Both barrels having been discharged, to reset the sears for further discharge the bridge-bolt is vibrated, as previously described, moving its extension 42 into contact with the lug 44 on the tripper-spring, throwing the tripper-block out, so that when the hammers are cocked the intermediate nose projection 51 on the tripper-block will lie against-the left-hand sear-point 54. The parts are'now in position to be operated so that the left-hand sear can he initially used for the purpose of discharging, first-,the left-hand barrel and, secondly, by a second complete vibration the left-hand barrel. The hammers being cocked as in Fig. l, vibration of the left orrear trigger causes the lug'17 on the trigger-shank '8 to-vibrate the left-hand sear,-it being under:

stood that the rear ends of both sears are at this time elevated to almost their complete upward movement and that but very little further movement is necessary to free the hammer. Discharge of. the left-hand barrel brings the recess 28 in the hammer into line with the forward end of the left-hand sear l9, permitting the sear-spring to vibrate the rear end of the sear downwardly, when the searpoint 54 wili pass the projection of the tripper-block, as shown in Fig. 8, placing the parts in position, so that by a .further complete vibration of the left or rear triggerthe righthand barrel can be discharged.

Itis apparent that by reason of the fact that both sears can beindependently vibrated either barrel can be discharged by either trigger-that is to say, the left-hand barrel can be discharged by the left-hand or rear trigger and the right-handbarrel discharged by the right-hand trigger-so that in addition to the interchangeability of the discharge previously described the gun can be used in the ordinary way.

Instead of employing the mechanism hereinbefore described in connection with the gun adapted to have barrels discharged in series, as'before explained, it is clear that the improvements can be utilized with a single-trigger gun and multibarrels for discharging the barrels in set sequencesnamel y, either left and right always or right and left always,

dependingupon which seat the trigger is adaptedtobeinitiallybroughtincontactwith.

too

It is apparent that many changes and modifications can be made in my invention and it may be otherwise embodied without departing from the spirit thereof.
